Green energy can be generated from a wide range of sources including wind, solar, hydro, tidal, geothermal, and biomass. Green energy is a renewable energy which generated from natural resources like sunlight, wind, rain, tides, waves, and geothermal heat etc. By using more renewable sources to meet its energy needs, world can lowers its dependence on fossil fuels and makes energy generation more sustainable. The green energy industry also drives technological innovation and employment across Europe. Green energy posses a natural process that do not create any type of pollution.

Green energy market is mainly driven by growing awareness regarding environmental concerns, rapidly depleting conventional resources of energy, favorable government policies, etc. Government initiatives and funding has provided strong boost to green energy market in Europe and North America. Stringent environmental regulations in these regions are major driving factor for green energy market. High initial investment and higher cost of energy is expected to hamper growth of this industry to some extent. However, increased research and development activity in the field of green energy is expected to lower down overall cost of green energy in the years to come. This is expected to fuel further growth of green energy market across the world between 2015 and 2020.

Based on types, green energy market can be segmented as solar photovoltaic, hydropower, wind energy, bio-fuels and geothermal. Hydroelectric power dominated the green energy market with large market share in total revenue generated in 2014. However, solar PV is expected to exhibit strong growth during the forecast period. Solar PV's are gaining popularity among end users owing declining cost and increased efficiency.

On the basis of end-users segment, green energy market is classified into residential, commercial and industrial end users. Commercial and industrial end user segment together accounted for largest share of total revenue generated in 2014. Commercial segment was the largest end-user segment in 2014. North America dominated the global green energy market with over 30% share in total revenue generated in 2014. However, with increased government support and investment in the field of research development, Asia Pacific is expected to witness robust growth during 2015 to 2020. Europe, Latin America and Middle East & Africa are also expected to experience significant growth of green energy market in the years to come.
